Title: Adjustable chair for sitting and reclining purposes
IPC: A47C1/035
Filed: 1935-11-19
Abstract: 469,313. Adjustable seats. LUCKHARDT, H., and LORENZ, A. Nov. 19, 1935, Nos. 32067 and 32068. Convention dates, Nov. 22, 1934 and June 22, 1935. [Class 52 (ii)] An adjustable chair comprises a rigid supporting frame on which movable seating parts comprising seat, back-rest and leg-rest, pivoted together, are supported and arranged in such manner that when the chair is moved from sitting to reclining position the seat is tilted backwards and the leg-rest is raised through an angle . greater than that through which the backrest is lowered. Fig. 3 shows a chair having seat 1, back-rest 2 and leg-rest 3 supported by the arm-rests 49 which are pivotally mounted on the rigid frame 15 at 48. When the position of the chair is altered the seat 1 is guided by means of a cam 36 arranged on its underside and co-operating with a cross-bar 50 on the frame 15. In the arrangement shown in Fig. 4, the supporting frame 33 has the arm-rests 34 formed integrally therewith, the back-rest 2 being pivotally supported thereon at 39 and the seat 1 being provided with a guiding surface 36 co-operating with a cross-bar 37, clamping means 38 being provided. Movement of the leg-rest 3 is controlled by a link 35 which joins the leg-rest to the lower end of the back rest. Fig. 9 shows a chair in which a guiding cam surface 53 on the arm-rest 43 co-operates with the apex 44 of the supporting frame 41. A roller may be provided at this point to cooperate with 53. The movable seating parts are pivotally supported on the frame 41 at the junction of the seat and back-rest. Alternatively the supporting point may be situated in the seat, when the chair will function as a rocking chair, clamping means for arresting movement of the seat and leg rest being therefore provided. In the alternative arrangement shown in Fig. 6, the arm-rest 43 slides on the vertex 44 of the frame 41 a pin secured on this apex co-operating with a slot in the arm-rest and selectively engaging sockets suitably disposed in the arm-rest. The Specification as open to inspection under Sect. 91 also describes a chair having a rigid supporting frame 15 Fig. 15 (Cancelled) on which the seat 1 and back-rest 2 are slidably supported, and provided with a member 16 having a guide slot 17 controlling the movement of a braking member 4. Various methods of controlling the movements of the seating parts of an adjustable chair are also shown diagrammatically. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to reciprocating internal combustion engines having decompressing mechanism
IPC: F01L13/08
Filed: 1948-12-14
Abstract: 652,085. Starting. RICARDO, H. R., and   GOLDSMITH, C. N. Dec. 14, 1048, No. 32320. [Class 7(v)] In an engine having decompressing mechanism to hold the inlet, exhaust, or a separate decompressing poppet valve open at starting, an inertia mechanism moved by and responsive to the speed of movement of a moving part of the engine automatically moves the decompressing mechanism from its starting to its running position above a predetermined engine speed. In Figs. 1 and 2 a lever E<SP>2</SP> is moved at starting to engage a notch F<SP>4</SP>, whereby a shaft C<SP>1</SP>, on which a rocker arm B is eccentrically pivoted, is rotated so that the valve A is held open, and a weight H<SP>2</SP> pivoted on a shaft H is then moved to the left so that an arm H<SP>1</SP> contacts the tappet D. When the engine is rotated the weight H<SP>2</SP> is reciprocated until at a predetermined speed its momentum carries it over the dead-centre position and it drops to a horizontal position in which a cam surface H<SP>4</SP> thereon moves a rod J inwardly to disengage the lever E<SP>2</SP> from the notch F<SP>4</SP> so that it is returned by a. spring C<SP>2</SP> to the notch F<SP>3</SP>, setting the rocker arm B in its normal running position. The weight H may be actuated by a cam on an overhead cam shaft. In a modification, Fig. 6, a lever L<SP>2</SP> rotates the eccentric pivot L of a rocker arm K<SP>2</SP> to adjust the exhaust valve timing to provide an increased compression ratio during the starting period as described in Specification 639,756, and the exhaust valve K is held open at starting by a cam N<SP>1</SP>. The inertia weight is actuated by a flange K<SP>4</SP> on the push rod K<SP>3</SP> and contacts a finger on the shaft N to move the cam N<SP>1</SP> clear of the arm K<SP>2</SP> at the predetermined speed.

Title: Improvements in or relating to public address stabilizing systems
IPC: H04M9/08
Filed: 1937-11-24
Abstract: 486,290. Public address and like systems. RADIO CORPORATION OF AMERICA. Nov. 24, 1937, No. 32381. Convention date, Nov. 28, 1936. [Class 40 (iv)] [Also in Group XL] To prevent singing in public address and like systems, the low frequency component of the input is filtered out and used to control the amplifier which amplifies the high frequency component only. The output of microphone 10 is passed to high-pass and lowpass filters 12 ... 14 and 20 ... 22. Valve 15 is normally biassed to cut-off. The low frequency component is amplified by 19 and rectified by 23 and the rectified current is used to make the control grid of valve 15 more positive so that the high frequency component is amplified and actuates loud-speaker 11. As no low frequency component is fed to the loud-speaker, signals from it picked up by the microphone cannot reach rectifier 23 and interaction is prevented. Specifications 279,452 and 282,675, [both in Class 40 (v)], are referred to.

Title: Resetting apparatus, more particularly for use in printing motion pictures
IPC: G03B27/16
Filed: 1939-12-29
Abstract: 536,464. Photographic printing apparatus. TECHNICOLOR MOTION PICTURE CORPORATION. Dec. 29, 1939, No. 33033. Convention date, March, 11. [Classes 98 (i) and 98 (ii)] Apparatus for successively resetting a mechanical element in response to periodic impulses, more particularly for use in printing kinematograph films, comprises a reciprocable controller which is retracted and returned, e.g. under spring action when the impulse ceases, at each impulse ; a controller gauge having a series of preferably adjustable or inter-change able stops of different length to limit the return movement of the controller ; means for moving the gauge during the retraction of the controller to set a different stop in the return path of the controller ; and means actuated on the return movement of the controller to reset the controlled element to an extent determined by said movement. The last-mentioned means may comprise an actuator, reciprocable in the same manner as the controller under the action of the impulse, and adapted on its return movement to set the controlled element; and an actuator gauge (e.g. a series of stepped stops) which is moved in accordance with the return movement of the controller and limits to an extent determined by said movement the return movement of the actuator. The invention is shown as applied to a kinematograph film printer, e.g. of the kind described in Specification 536,465 for the purpose of changing the intensity of the printing light for sections of a negative having different densities. The negative 3 is provided with the usual notches 2 for initiating the changes, co-operating with a spring-urged switch arm 1 which close a relay circuit 4 on the arrival of a notch and energizes solenoids 9, 10. Solenoid 9 retracts against spring action a controller rod 14 carrying an arm 16 adapted normally to rest on one of a series of interchangeable stops 12 of different length on the periphery of a rotary gauge disc 11 which is fast with a ratchet wheel 17 co-operating with a pawl 19 pivoted on an arm 18 turning on the same pivot as the wheel. The arm 18 has a cam edge 20 which is engaged by a pin 21 on the rod 14 when this is retracted, thereby stepping the disc 11 round so that the next stop 12 is in position to arrest the arm 16 on the rod 14 when this returns after cessation of the electromagnetic impulse. Solenoid 10 similarly retracts against spring action an actuator rod 33 geared to a disc 31 carrying a polarisation filter 32 which is disposed in the path of the printing light beam. The return movement of the rod 33 after cessation of the electro-magnetic impulse rotates the filter 32 through an angle depending on the return stroke of the rod, and this is determined by one of a series of stepped stops 36 on a rotary gauge disc 35 which is angularly adjusted by gearing 37 .. 40 in accordance with the return stroke of the controller rod 14, as limited by the particular stop 12 in operation.
